MIXER FOR GAsEoUs FLUIns.

Application filed February 24,

Be it known that I, CHARLES H. Mrnns,.a citizen of the United States, residing a* Buffalo, in the county of Erie and State of New York, have invented a new and useful Mixer for Gaseous Fluids, of which the fol lowing is a specification.

1` his invention relates to means for mixing air and gas rior to the admission of the saine to the combustion chamber of an explo sive engine, and consists in certain novel features which will be hereinafter first fully described and then pointed out in the, claims.

ln the annexed drawings, which fully illustrate my invention, Figure 1 is a side elevation of the improved device. Fig. 2 is a central vertical section of the same. Fig. 3 is a horizontal section taken on the line 8-.% of Fig. 2. Fig. 4 is a detail perspective view of the outer' sleeve. Fig. 5 is a detail per'- spective view of the inner sleeve. Fig. (3 is a detail perspective view of the tube constituting the passage for the Fig 7 is a detail perspective view of the clamping nut.

1n the drawings, l have indicated a portion of a gas generator or carburetor' 1, which may be of any desired type, being shown only for the purpose of indicatingthe application of my invention, and the construction of which it is not necessary to describe. Leading from any convenient point of the generator is an elbow or tube 2 to the end of which is secured a cup-shaped coupling 3 .containing a screen et to filter the gas on its passage to the engine, and in the base of this coupling I secure a plate 5 in which is centrally litted a gas tube G which may be of any desired dimensions and is provided at a point about midway its ends with openings or ports 7 while to its lower end is secured a coupling 8 from which the pipe 9 leads to the combustion chamber of the engine.

Disposed concent-rically around the gas tube G but spaced from the same is an air tube 10 provided with notches or ports 11 at its lower end, andk around the said air tube against the same is a damper or regulating sleeve 12 provided at its lower end with notches or port-s 13 adapted to register with the ports 11 in the air tube 10, or to register with portions of the tube between the said ports so as to cut off the iiow of air, as will be readily understood.

At its upper end this damper or regulating Specification of Letters Patent. 1910, Serial No. 545,776. Renewed March 7, 1913. Serial No. 752,787.

witlu so that when the Patented @et 14,1913.

sleeve is provided with a milled flange or head 14, by means of which it may be rot-ated upon the said sleeve 10 to adjust the device so as to control the admission of air.

My device is intended more particularly for use in connection with motorcycles and" I, therefore, purpose to have the damper held in its position after justed so as to obtain the most satisfactory results from the engine, and to this end l mount a securing nut 15 upon the gas tube 7, which nut is adapted to be turned home against the lower 4ends of the air tube 10 and the damper 12 so as to bind the same against the plate and the coupling 3 sufliciently to hold them in their adjusted positions.

The operation of the device will be readily understood. The gas is drawn through the gas tube 6, the coupling t., and the pipe 9, into the explosive chamber of the engine, in the ordinary manner by the suction of the engine. Air admitted through the registering ports 1l and 13 will pass up between the gas'tube and the air tube and enter the gas tube through the port i' so as to mingle with the and become thoroughly mixed theremixture is admitted into the combustion chamber of the engine, it will have the proper proportions of air and gas to obtain the desired results. By having the ports in the gas pipe arranged some slight distance above the lower end thereof, the air is not drawn directly to the engine but will travel a short distance with the gas so as to be thoroughly commingled therewith when it enters the engine.

The coupling S is in the forni of a T-litting and on the outer end of the said coupling 1 secure a cap or thimble 16v provided with openings 17 in its side and having a valve stein 18 slidably mounted in its outer end. A valve 1) is carried by the said stein and is normally held against the end of the coupling 8 by a spring 2O coiled around the said stem between the valve andthe end of the thimble, as clearly shown in Fig. 2.

Should there be an excessive back pressure from the engine, this pressure will overcome the tension of the spring 20 so as 'to unseat the valve, and the back-fire or unconsumed gases will consequently escape through the openings\17. All liability of any damage occurring to the engine is thus obviated.

My improved device is extremely simple in its construction and its advantages are it has been adtaought td be obvious. The parts canv be readily assembled and the damper can be adjusted by means of the milled head Witliout the rider being obliged to dismount and the `trictional engagement of the retaining nut with the lower end of the damper will sufl'ice to hold it in the position to which it has been adjusted. Damage to one part of the device will not necessarily involve the replacement of any other part. r

llaving thus described the invention, what I claim as new, and desire to secure by Letters Patent, is

l. In a device for the purposedescribed,

^ a gas tube, an air tube surrounding the gas with notches at one endv .constituting ports, the gas tube and air tube tube and provided communicating, a damper on and rotatable about the air tube and provided with matching notches constituting ports, a closure for the end of the air tube and of the damper remote :trom the end provided With the y notches, a closure for the notched ends of the air tube and damper movable toward and from the lirst named closure to lock the damper against rotation and to release it to rotation in accordance with the direction of movement o't the second named closure, and means for supporting the closures.

2. In a device for the purpose described, an air lube having ports at the lower'end, a dan'iper rotatable on the air tube and provided with matching ports, and a gas tube interior to and concentric with the air tube and provided with ports intermediate of the length of the said air tube, and an atljustable mein-ber mounted on the gas tube and adjustable in the direction of the longitudinal axis thereof into clamping relation to the damper, said adjustable member constituting a closure tor the lower ends of thel air tube and damper.

'The conibination ofa gas tube having ports, a supply `coupling communicating with the upper end of thc gas tube, an air tube arranged concentric with the gas tube and spaced tl'ierefrom and provided with ports, a damper rotatably 1fitted on the air tube and provided with ports adapted t0 register with the ports in the airtube, and a nut titled on the gas tube and bearing against the lower ends ol the air tube and the rying it to move damper to clamp the same against the couplingon the -upper end of the gas tube.

4. The combination of a coupling, a plate secured within the same, a gas tube centrally fitted to the plate and communicating with the interior ofthe coupling, and provided with ports at an intermediate point of its length, an air' tube spaced from the gas tube and concentric with the same and having ports at its lower end, a damper or regulating sleeve tting the air tube closely and provided with p orts registering with the ports of the air'tube, a nut threaded on the gasl tube and adapted to bear against the lower ends of the damper and air tube, and a milled head on th damper by which it may be rotated.

5. The combination of a coupling, a gas tube centrally fitted to and communicatingA with the interior of the vided with ports, the gas tube and concentric with the same and having ports at its lower ehd, a damper or regulating sleeve fitting closely and provided with ports registering with the ports of the air tube, a nut threaded on the gas tube and adapted to bear against the lower ends ot' the damper and air tube, and means provided on the damper by which it may be rotated.

6. In a device for the purpose described, a gas tube having. intermediate ports and au elongated threaded portion at one end, an

coupl ing and pro- 'air tube concentric with and spaced from the gas tube and provided at one end with notches constituting ports, a damper cX- terior to the air tube and rotatable thereon and provided with matching notches conan air tube'spaced from the air tube stituting ports, and an adjustable member mounted o-n the threaded end of the gas tube and constituting a closure for the notched ends of the air tube and damper, and adjustable on the portion of the gas tube carinto clamping relation to the damper. In testimony, that I claim the foregoing as my own, I have hereto affixed my signature'in the presence of two witnesses.
